Type designation
BRDLW- (rated voltage:kV)/ (rated current:A)- (Antifouling grade)
BR-OIP Condenser transformer bushing,OIP Condenser wall bushing represent as CR
D-Short tail bushing,if no "D" it should be Medium-short tail bushing
L:can install CT
W:Antifouling type,3 means creepage distance is 25mm/kV,4 means creepage distance is 31mm/Kv
